Architecting Applications for the Web
Lab 03
Interceptors and Tags
Mục tiêu
-
Sử dụng Interceptor thừa kế Struts-default và xây dựng 1 custom interceptor
Sử dụng struts-tags để xây dựng các trang jsp
Phần I Bài tập step by step
Bài tập: xây dựng các chức năng register,search,update,delete user.
Dùng các Interceptor để filter khi user login và giữ lưới dữ liệu khi
update, delete user
Phần 1: Xây dựng các chức năng register,search,update,delete User
Step 1: Sử dụng Tags để xây dựng giao diện

<result name="success">success.jsp</result>
<result name="error">error.jsp</result>

<action name="SearchUser" class="Session2.Session2Action" method="searchUser">
<result name="success">searchuser.jsp</result>

<action name="deleteUser" class="Session2.Session2Action" method="deleteUser">

<action name="updateUser" class="Session2.Session2Action" method="updateUser">

Search, Delete, Update User:
Phần 2: Dùng các interceptor
Srep 1: Trong phần 2 ta đã sử dụng Interceptor chaining để keep data khi ta update và
delete user
Step 2: Tạo custom interceptor để tính thời gian login khi login: Source Packages new
other Struts2 Interceptor Name: LoginInterceptor, package: Interceptor
- LoginInterceptor.java:
package Interceptor;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;
/**
*
* @author DELL
*/
public class LoginInterceptor implements Interceptor {
public LoginInterceptor() {
}
@Override
public void destroy() {
System.out.println("Destroying MyLoggingInterceptor...");
}
@Override
public void init() {
System.out.println("Initializing MyLoggingInterceptor...");
}
@Override
public String intercept(ActionInvocation actionInvocation) throws Exception {
String className = actionInvocation.getClass().getName();
long startTime = System.currentTimeMillis();
IT Research Department

Trang 13 / 14

System.out.println("Before calling action: " + className);
String result = actionInvocation.invoke();
long endTime = System.currentTimeMillis();
System.out.println("After calling action: " + className
+ " Time taken: " + (endTime - startTime) + " ms");
return result;
}
}
Step 3: Cấu hình file Struts.xml
<interceptors>
<interceptor name="mylogging" class="Interceptor.LoginInterceptor"></interceptor>
<interceptor-stack name="loggingStack">
<interceptor-ref name="mylogging"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>

<result name="error">loginfailure.jsp</result>
